  public RequestUtil()

Method Detail

• filter

  public static String filter(String message)

  Filter the specified message string for characters that are sensitive in HTML. This avoids potential attacks caused by including JavaScript codes in the request URL that is often reported in error messages.

  Parameters:

  message - The message string to be filtered

• parseParameters

  public static void parseParameters(Map<String,String[]> map,
                     String data,
                     String encoding)

  Append request parameters from the specified String to the specified Map. It is presumed that the specified Map is not accessed from any other thread, so no synchronization is performed.

  IMPLEMENTATION NOTE: URL decoding is performed individually on the parsed name and value elements, rather than on the entire query string ahead of time, to properly deal with the case where the name or value includes an encoded "=" or "&" character that would otherwise be interpreted as a delimiter.

  Parameters:

  map - Map that accumulates the resulting parameters

  data - Input string containing request parameters

  encoding - The encoding to use; encoding must not be null. If an unsupported encoding is specified the parameters will not be parsed and the map will not be modified

• parseParameters

  public static void parseParameters(Map<String,String[]> map,
                     byte[] data,
                     String encoding)
                              throws UnsupportedEncodingException

  Append request parameters from the specified String to the specified Map. It is presumed that the specified Map is not accessed from any other thread, so no synchronization is performed.

  IMPLEMENTATION NOTE: URL decoding is performed individually on the parsed name and value elements, rather than on the entire query string ahead of time, to properly deal with the case where the name or value includes an encoded "=" or "&" character that would otherwise be interpreted as a delimiter. NOTE: byte array data is modified by this method. Caller beware.

  Parameters:

  map - Map that accumulates the resulting parameters

  data - Input string containing request parameters

  encoding - The encoding to use; if null, the default encoding is used

  Throws:

  UnsupportedEncodingException - if the requested encoding is not supported.
